Cereal rusts and powdery mildews are very important diseases occurred on the cereal crops, which caused yield losses at 5-10% in general and even more than 30% while severe epidemics occurred. In recent years, with the global climate change, change of cultivation system and evolution of the pathogens, the world is facing great challenges caused by cereal diseases.展开更多

Nearly 650 participants from more than eight countries （regions） and international organizations attended this conference. The conference provided an communication platform for international counterparts, and the content was closely related to all aspects of dairy cow health, including dairy mastitis pathogens, diagnose, therapeutics, management, residue, bacterial resistance and milk safety. Here we are pleased to have the opportunity to organize a special focus and provide the most updated knowledge of the given topics.展开更多

Study on climate change has increasingly become a frontier for academics and scholars in all fields. From subjective judgment to objective measurement,CSSCI journal papers collected from the CNKI database in 1996-2016 were used. With the aid of bibliometric tools,it is a new attempt to explore the development thread of domestic climate change research and recent research hot spot within the framework of the climate change subject. It found that the current problems in the field of climate change research in China are as follows:(i) low research level and unbalanced discipline development,(ii) relatively spatially concentrated research institutions and relatively research direction,and(iii) single research perspective of the field of agricultural climate change and lack of agricultural adaptability studies.展开更多
